DOI: 10.1117/1.oe.57.8.084103
Abstract: Abstract. Determination of intrusion location in a phase-sensitive optical time-domain reflectometer is important and fundamental. In general, the spatial resolution of event location is limited by the temporal width of the probe pulse. We found… read more here.
